Not installable in QGIS 3

[kgraefe]

The plugin is not available in the plugin list in QGIS and manual installation from the ZIP file fails with the following error message:

ModuleNotFoundError: No module named 'tilemapscaleplugin' 
Traceback (most recent call last):
  File "C:/PROGRA~1/QGIS3~1.0/apps/qgis/./python\qgis\utils.py", line 336, in startPlugin

FYI, I am working on Qgis3 compatibility at https://github.com/kgraefe/TileMapScaleLevels/tree/develop

It is working quite well already. I just have to figure out why it's crashing when zooming out too far.
